PROBLEM TO BE SOLVED: To provide a pen having a stick-shaped core in which man-hour of production is reduced and processes are easily automated by forming the core by injecting fused raw materials into a container in a state where all main components of the container are assembled. SOLUTION: The pen includes a stick-shaped core 50, a hollow container 10 of which the both ends are opened, a hollow holding shaft 30 which is inserted into the container to freely linearly move in the axial direction and in which a central hole 42 is formed by passing through the inside, and a hollow feeding member 70 which is coupled to the tail end of the container 10 to freely rotate and of which the both ends are opened to linearly move the holding shaft 30 inside of the container 10 and to communicate with the central hole 42 in accordance with the rotation. The core 50 is solidified after injected from the tail end of the feeding member 70 through the central hole 42 into the container 10 while fused, and its tail end is held on the top of the holding shaft 30, such that the core 50 moves while being linked with the movement of the holding shaft 30.
